switch for case sensitivity

[David Relson]

Greetings,

I seemed to have stirred up the traditional hornet's nest with 
-Pu/-PU.  The consensus seems to be that -Pf/-PF is preferabl, where '-Pf' 
enables case folding and '-PF' disables case folding.  Bogofilter's current 
behavior is '-Pf', also known as case folding and being sensitive.

A few minutes ago, the phrase "mixed case" came to mind.  "-PM" would 
disable it (providing case folding) and "-Pm" would enable it (giving case 
sensitivity).

Is this good, bad, or something else?  Assuming it's good, is it preferable 
to -Pf/-PF or would people prefer that bogofiler use -Pf/-PF ???
